In ‘Melancholia,’ Lars von Trier has created a deeply personal examination of the the extremes of depression. Is the end of the world real or metaphorical? Is the science behind it sound? These questions are ultimately irrelevant, as the movie forces the viewer to deal with fear on a personal level as well. This isn’t a film about the “global” end of the world. It’s a film about what the end of the world inside one person feels like.
